IMPROVED REGTIE'IER FOR STILLS- I fill $ltimlt retreat to in that isms an: m linking part at figs same.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, A. WERNIE, of New York city, in thecounty of New York, and Stateof New York, have invented a new and improved Rectifier; and I do hereby declare that the following is .a full, clear,'and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 represents a vertical cross-section of my improved rectifier.'

Figure 2 is a plan or top view of the same.

Similar letters of reference indicate like parts.

The object of this invention is to so arrange a rectifier or doubler, through which the vapors-are-conducted in their passage from the still to the worm, that the low wines will be quickly and completely separate and retained.

A 'is the rectifier, whichis an upright cylinder, made of wood or copper. The vapors are conducted from the still to the bottom of the rectifier through a pipe, d. The vapors, in ascending the cylinder, are prevented by an annular plate, 5, which is secured to the inner'wall of the cylinder, from ascending too fast. The annular plate b inclines downward towards the centre, as'seen in fig. 1. The vapors then come in contact with a copper box, B, which is supported by brackets 1: attached to the inside of the cylinder. The box Bis filled with cold water, which passes continually through it in a'manner hereafter described. The box 13 is of a smaller diameter than thecylinder, so that sufficient spaceis left around the rim of the box for the vapors to pass through. The vapors next strike against the covering plate C of the rectifier, which is also cooled by cold water, and are then carried off to the worm through a pipe, D. The water is conducted to the centre of the covering plate 0, and is then guided through a spiral channel, formed by copper bands d, which are set on the cover 0, as seen in the drawings. At the'end of the spiral channel the water is drawn of through a tube, e. Asimilar arrangement is provided in the box B. The water is conducted to the centre of the same through an elbow tube,f, and then passes through a spiral channel, which is formed by the upright flanges g, and is then drawn off through a pipe, h. The cover is well secured to the cylinder by means of metal rings E, which are laid respectively below and above the flanges i on the cylinder and cover, and which are held together by bolts and nuts K, as seen in figs. 1 and 2. By the arrangement of the spiral channels the cooling surfaces are equalized, and the water is allowed to pass off as soon as it becomes warm, while none of the cool water is, thrown away, as' is nsuallydone thereby a smaller quantityof water is used for cooling purposes than is used in the old devices where the warm and cold water becomes mixed. This apparatus occupies less room than those heretofore used. It can be easily cleaned, which is not the case with any other rectifier. It can be easily taken apart for repairing or other purposes. The improvements can be applied to old doublers or rectifiers without much expense or loss' of time. This apparatus is also considerably cheaper than the common ones.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. I claim the spiral channels formed on the covering plate 0 and in the box B by the spiral flanges d and g, respectively, substantially as and for the purposeherein shown and described.

2. l'claim the annular plate 6, made substantially as andfor thepurpose herein shown and described.

3. I claim the combination of: the plate 6, box B, and cooling'cover G, with the rectifier A, substantially as and forthe purpose herein shown and described. I
